Description

The invention relates to a wheel suspension for a vehicle, with a steering knuckle carrier, in which two hole openings are provided which lie opposite one another in an axial direction and which form openings of one or at least one mounting hole provided in the steering knuckle carrier and extending in the axial direction, two axially spaced apart arranged axle bolts extending in the axial direction and engaging through the hole openings into the mounting hole, and a chassis component which is pivotably mounted on axial end sections of the axle bolts about a pivot axis extending in the axial direction relative to the steering knuckle carrier.

The EP 1 513 719 B1 discloses an arrangement for the steerable suspension of a motor vehicle wheel, comprising a first bearing and a second bearing, arranged on a support unit in order to form a geometric axis of rotation around which a motor vehicle wheel is mounted in bearings in bearings that can be steered with respect to the support unit, which has a support surface. The first and the second bearing each have an inner ring with an outer, radially oriented surface which is arranged in such a way that they adjoin the support surface and rest against it in order to absorb forces that act radially with respect to the geometric axis of rotation. The supporting surface of the supporting unit is designed in the shape of a cylinder jacket and at the same time forms the inner wall of a through hole extending in the direction of the geometric axis of rotation. The surfaces of the two inner rings, which adjoin the wing and rest against it, are also designed in the shape of a cylinder jacket. Specifically, the two surfaces of the inner rings, which adjoin the support surface and bear against it, form neck sections of the inner rings, the neck sections being inserted into opposite hole openings of the through-hole.

With steerable suspensions of motor vehicle wheels mounted in this way, an impermissibly high surface pressure can occur in the supporting surface of the support unit during driving operation, in particular when high lateral forces act on the motor vehicle wheel. The two edges of the through-hole, which are opposite in the direction of the axis of rotation and at which it emerges from the support unit, are particularly at risk. The above-mentioned inadmissibly high surface pressures can cause plastic deformations of the hole openings of the through hole and lead to a safety-critical loosening of the steerable suspension of the motor vehicle wheel.

Proceeding from this, the invention is based on the object of providing a mounting of the steerable motor vehicle wheel suspension in which impermissibly high surface pressure values in the area of the hole openings of the through-hole are avoided.

This object is achieved by a wheel suspension according to claim 1. Preferred developments of the wheel suspension are given in the subclaims and in the following description.

The initially mentioned wheel suspension for a vehicle, with a steering knuckle carrier, in which two hole openings are provided which lie opposite one another in an axial direction and which form openings of one or at least one assembly hole provided in the steering knuckle carrier and extending in the axial direction, two axially spaced apart , axle bolts extending in the axial direction and engaging through the hole openings into the mounting hole, and a chassis component which is mounted on axial end sections of the axle bolts so as to be pivotable about a pivot axis running in the axial direction relative to the steering knuckle carrier, is in particular further developed in that the Hole openings each have a first contact area with a conical inner circumferential surface, the conical inner circumferential surfaces of the first contact areas tapering towards one another in the axial direction, and the axle bolts each having a second contact have areas with a conical outer peripheral surface, wherein the conical outer peripheral surfaces of the second contact areas taper towards one another in the axial direction and bear against the conical inner peripheral surfaces of the first contact areas.

The surface pressure that occurs in the area of the hole openings can be reduced by the conical surfaces. This results in an overall more wear-free and thus more reliable wheel suspension.

One or any direction running transversely to the pivot axis and / or to the axial direction is referred to in particular as a radial direction. The conical inner circumferential surfaces of the first contact areas and the conical outer circumferential surfaces of the second contact areas are preferably rotationally symmetrical with respect to an axis of symmetry running in the axial direction. The mounting hole is preferably rotationally symmetrical with respect to the axis of symmetry. The axis of symmetry advantageously extends centrally through the hole openings. The pivot axis is or forms, in particular, the axis of symmetry.

The steering knuckle support is preferably made of metal, in particular an iron material such as steel. The first contact areas are formed, for example, by the steering knuckle carrier and / or by the material of the steering knuckle carrier. For example, the steering knuckle carrier in or at least in the contact area consists of a hardened material, such as cast iron with spheroidal graphite.

According to one embodiment, in particular two conical disks are inserted into the hole openings, on which the first contact areas and / or the conical inner peripheral surfaces of the first contact areas are provided. The first contact areas are preferably formed by, preferably two, conical disks inserted into the hole openings or by the conical disks inserted into the hole openings. For example, the first contact areas are formed by the material of the conical disks. The conical inner circumferential surfaces of the first contact areas are preferably provided on the conical disks. It is thus possible to produce only the conical disks and not the entire steering knuckle carrier from a high-strength material. The conical disks are preferably made of metal, in particular of an iron material such as steel. For example, the conical disks are made of high-strength, tempered steel. The conical disks are preferably rotationally symmetrical with respect to the axis of symmetry.

The axle bolts are preferably made of metal, in particular an iron material such as steel. For example, the axle bolts are made of high-strength, tempered steel. The second contact areas are e.g. formed by the axle bolts and / or by the material of the axle bolts. The axle bolts are preferably rotationally symmetrical with respect to the axis of symmetry.

According to a further development, each of the conical disks, in particular with respect to the pivot axis, is connected to the ash leg carrier in a rotationally rigid manner. The conical disks preferably each have a cylindrical tube section at their, preferably in the axial direction, facing, in particular axial, ends, which, for example, in the area of the hole openings and / or within the mounting hole, with its outer circumferential surface, preferably forming a press fit, on the steering knuckle carrier is applied. With this design of the conical disks, e.g. the conical disks can be secured against twisting with respect to the steering knuckle carrier. This anti-rotation lock is in particular frictional. Alternatively, a form-fitting anti-rotation device, for example by means of a serration, is possible. If the conical disks each have a cylindrical pipe section at their axial ends facing one another in the axial direction, the outer circumferential surface of which rests against the steering knuckle carrier in the area of the hole openings and / or within the mounting hole, forming a press fit, this has the advantage that the steering knuckle carrier together with the conical disks pressed into it, forms a preassembled structural unit, which has an advantageous effect in the assembly process. Another advantage of the aforementioned press fit is that when the axle bolts are screwed into the mounting hole, the conical disks are prevented from turning.

According to one embodiment, it is provided that the steering knuckle carrier has a third contact area with a conical inner circumferential surface at each of the hole openings, the conical inner circumferential surfaces of the third contact areas tapering towards one another in the axial direction, and the conical disks each having a fourth contact area with a conical outer circumferential surface, wherein the conical outer circumferential surfaces of the fourth contact areas taper towards one another in the axial direction and bear against the conical inner circumferential surfaces of the third contact areas. The third contact areas are formed e.g. by the steering knuckle carrier and / or by the material of the steering knuckle carrier. Furthermore, the fourth contact areas are formed, for example, by the conical disks and / or by the material of the conical disks. The conical inner circumferential surfaces of the third contact areas and the conical outer circumferential surfaces of the fourth contact areas are preferably rotationally symmetrical with respect to the axis of symmetry.

According to a further development, it is provided that the steering knuckle support, in particular within the assembly hole, in the area of the hole openings each have a fifth contact area with a cylindrical inner circumferential surface, which axially adjoins the respective third contact area, the fifth contact areas being arranged between the third contact areas. Each axle bolt advantageously has a sixth contact area with a cylindrical outer circumferential surface, which axially adjoins the respective second contact area, the sixth contact areas being arranged between the second contact areas. The conical disks preferably have at their, preferably in the axial direction, facing, in particular axial, ends in each case the or a cylindrical pipe section which, preferably in each case forming the or a press fit, on the cylindrical inner circumferential surface of the respective fifth contact area and on the cylindrical Outer circumferential surface of the respective sixth contact area rests. The fifth contact areas are formed, for example, by the steering knuckle carrier and / or by the material of the steering knuckle carrier. Furthermore are the sixth contact areas are formed, for example, by the axle bolts and / or by the material of the axle bolts. The fifth contact areas preferably have a larger diameter than an area of the assembly hole lying between the fifth contact areas. The cylindrical inner circumferential surfaces of the fifth contact areas and the cylindrical outer circumferential surfaces of the sixth contact areas are preferably rotationally symmetrical with respect to the axis of symmetry.

The axle bolts are, for example, screwed to the steering knuckle carrier and / or screwed into the steering knuckle carrier. The axle bolts are preferably screwed into the hole openings and / or into the mounting hole and / or through the hole openings into the mounting hole. The axle bolts are thereby preferably connected to the axle beam and / or screwed and / or screwed into this. In particular, each axle bolt has an external thread, which is for example a fine thread. The steering knuckle support preferably has one internal thread in the mounting hole or an internal thread for each axle bolt, which is for example a fine thread. Each axle bolt is preferably screwed with its external thread into the internal thread or threads of the steering knuckle carrier. The screw connections between the steering knuckle carrier and the axle bolts are and / or the screw connection between each axle bolt and the steering knuckle carrier is in particular self-locking. The threads of the axle bolts are preferably in the same direction. For example, the axle bolts either both have a right-hand thread or both a left-hand thread.

The at least one mounting hole can be formed, for example, by blind holes lying one behind the other in the axial direction. However, the mounting hole is preferably a single hole. In particular, the mounting hole is a through hole. The hole openings are preferably formed by axial ends of the mounting hole.

According to one embodiment, the axle bolts each have an axially continuous recess. An inner part is preferably provided which extends in the axial direction through the continuous recesses and / or through the axle bolts. The inner part is preferably made of metal, in particular of an iron material such as steel. The inner part is preferably rod-shaped. For example, the inner part forms a threaded rod. In particular, the inner part extends in the axial direction.

Preferably, two axial locks are provided on the inner part, between which the axle bolts are arranged and are thereby secured in the axial direction, in particular in a form-fitting manner, on the inner part. Thus, the axle bolts can be held together by the inner part even if at least one of the axle bolts should have become detached from the steering knuckle carrier.

The inner part is preferably connected in a rotationally rigid manner to one of the axle bolts, in particular with respect to the pivot axis. This makes it possible, for example, to axially preload the inner part by screwing it together without the inner part itself rotating. The inner part advantageously extends in the axial direction through the mounting hole.

According to a further development, a recess with an inner circumferential surface which is non-circular in cross section is provided in the end faces of the axial end sections of the axle bolts, on which a correspondingly shaped outer circumferential surface of an insert inserted into the recess and surrounding the inner part engages, which is preferably with the inner part, in particular with respect to the Pivot axis and / or the axis of symmetry, is torsionally rigidly connected. The non-circular inner peripheral surface of each recess is preferably a polygonal one, such as a hexagonal inner peripheral surface. Further, the correspondingly shaped outer peripheral surface of each insert is, for example, a polygonal, such as a hexagonal outer peripheral surface.

By engaging the outer circumferential surface of each insert on the inner circumferential surface of the respective recess, each insert is preferably connected in a torsionally rigid manner with the respective axle bolt, in particular with respect to the pivot axis and / or the axis of symmetry. For example, one or at least one or each of the inserts is formed as a separate component. In this case, the or the at least one or each insert is secured to the inner part in the axial direction, for example by one or at least one additional element. The or each additional element is or comprises, for example, a nut screwed onto one end of the inner part. Furthermore, one or another of the inserts can be formed integrally with the inner part and, for example, form a screw head of the inner part.

According to one embodiment, one or at least one or each of the inserts has a non-circular inner circumferential surface which engages in each case with a correspondingly shaped outer circumferential surface of an end region of the inner part. The non-circular inner peripheral surface of the or each insert has, for example, a flattening. Furthermore, for example, the correspondingly shaped outer peripheral surface of the or each end region of the inner part has a flattening. By engaging the inner peripheral surface of the or each insert on the outer peripheral surface of the or the respective end region of the inner part, the or each insert with the is preferred Inner part, in particular with respect to the pivot axis and / or the axis of symmetry, connected in a rotationally rigid manner.

According to a further development, a joint is arranged on each of the axial end sections of the axle bolts. The chassis component is preferably mounted pivotably about the pivot axis relative to the steering knuckle carrier by means of the joints on the axial end sections of the axle bolts. The axial end sections of the axle bolts advantageously extend, preferably in each case, in particular axially, out of the hole openings and / or out of the assembly hole. The hole openings and / or the mounting hole are preferably arranged, in particular thus, preferably axially, between the axial end sections.

The axial locks are formed, for example, by stops that are preferably firmly connected to the inner part and on which the axle bolts are supported in particular axially. For example, the stops extend radially away from the inner part. The axial locks preferably include the inserts and / or the additional element or elements. The axial locks are preferably formed by the inserts and / or by the additional element or elements, or vice versa. For example, the inserts are formed by axial projections provided on the axial securing devices and / or the stops, from which stop surfaces, for example, extend radially away, on which the axle bolts are particularly axially supported.

A rotary encoder is preferably provided, by means of which the rotation of the chassis component relative to the steering knuckle carrier about the pivot axis can be detected. For example, the rotary encoder is connected to the inner part and / or to one of the axle bolts and / or to one of the inserts and / or to the or one of the additional elements and / or to one of the joints.

The chassis component is e.g. a suspension arm, such as a wishbone. The chassis component is preferably a steering knuckle, which is also referred to as a wheel carrier. A vehicle wheel is preferably provided which is mounted on the steering knuckle so that it can rotate about a wheel axis of rotation. At least one or two or more chassis links are advantageously provided, by means of which or which the steering knuckle carrier, in particular articulated and / or moveable, is connected to a chassis. The suspension link or links are preferably one or each transverse link.
